angle of attack

基本解釋

Conversely, when under water it will need a negative angle of attack, so the craft will travel nose-down (see diagram).
相反，在水下，要求它有一個(gè)俯沖角，這樣飛行器在水里動(dòng)的時(shí)候前部向下傾斜。
So when the craft is airborne, the wing will need a positive "angle of attack": in other words, it will need to be angled upwards relative to the airflow.
所以，飛行器在空中飛行的時(shí)候，翅膀需要一個(gè)仰”沖角“——換句話說(shuō)，相對(duì)于氣流，飛行方向向上。
In the final test flights, the pilots were able to purposely exceed the normal limits of the aircraft in terms of variables such as angle of attack and side slip angle.
最后試飛時(shí)，飛行員能夠有意識(shí)的超過(guò)飛機(jī)正常飛行參數(shù)，例如迎角和側(cè)偏角的限制。

Just as in a plane, you can stall if you assume too steep an angle of attack.

the acute angle between the chord line of an aerofoil and the undisturbed relative airflow (Also called angle of incidence)

迎角
Within the field of ground effect, aerodynamic forces of the wing-in-surface effect crafts are not only decided by the angle of attack, but also by the flying height, and they lead to more complicated stability problems.
在地效作用區(qū)域內(nèi)，地效飛機(jī)的氣動(dòng)力不僅與迎角有關(guān)，而且與飛行高度有關(guān)，因而其飛行穩(wěn)定性問(wèn)題更為復(fù)雜。
